I haven't been in your situation, but I was married for 7 years to a man I wasn't entirely happy with, so I know where you're coming from. I know where you're going, too. Straight to hell, and I don't mean that in an evangelical, Bible-thumping way. I mean that you're on the slippery slope to a very bad place. DON'T cheat on your husband. It won't end well, and nobody will support you- you'll be a Fallen Woman.

This is, of course, assuming you are a woman. Your screen name isn't much help, and I notice that you don't actually say.....

If you're a guy, I guess it really doesn't change what I have to say. Nobody likes a cheater.
